52.28.2 Answer

Waits for an incoming voice call (circuit-switched or VoIP) to arrive and answers it when it arrives.

Configuration property:

Call Type:

Default: The type of voice call (CS or VoIP) is determined by a setting in the device, or by its capabilities.

VoIP UE: VoIP call using an on-device VoIP client.

VoIP PC: VoIP call using the VoIP client built into TEMS Investigation.

Codec: (Appears for certain VoIP clients) Voice codec, one of: G.711 A-law, G.711 μ-law, AMR-WB, AMR-NB, or EVRC-B. "Default" is the client's default codec, which means the one last used. If the VoIP client does not support codec selection, it always uses the default codec.

For certain codecs, this additional field appears:

Codec Rate: Voice codec bit rate.

Multi-party calling:

Disabled: Normal behavior, UE cannot answer another party during a call.

Merge: Enables conference calling. Use on the recipient in a 2-way voice call to answer a voice call from a third party to allow them to join the call, creating a 3-way conference call. (This party will "own" the conference.)
